BURNER.

Specification of Letters Patent.

Patented il an. 22., letal.

Y Application filed January 3, 1916. Serial No. 69,769.

To all whom it may concern:

Be it known that I, JOHN P. fllntmsniini,7 a citizen of the United States, and resident of the city of Providence, in the county of' Providence and State of Rhode Island, have invented certain new and useful lmprovements in Burners, of which the following is a specification.

This invention relates to improvements in oil burners of the class adapted to be applied to lamps or stoves for the purpose of increasing either their lighting or their heating efficiency.

The flame in the ordinary oil burning wick lamp is of a reddish cast which indicates imperfect combustion or the presence of unconsumed particles of carbon.

The object of this invention is to pro-vide an improved burner of this class designed to act upon and break up the flame and so permit the oxygen of the air to mix more thoroughlyv therewith to oXidiZe or decompose these unconsumed particles of carbon and so render combustion more perfect and produce a whiter light, thus materially increasing both the luminosity as well as ythe heat value of the flame over that obtained from the ordinary oil burner.

A further object of this invention is to provide my improved burner with a multiplicity of fingers or projections arranged to extend into or in proximity to the flame issuing from the wick so as to break up or separate the sheet of heated gases into a multiplicity of streams whereby the unconsumed particles of carbon are more thoroughly decomposed and combustion is more perfect.

A further object of this invention is the provision of a plate so located as to be heated to a high temperature by the flame and to provide this plate with a multiplicity of openings through which the atmospheric air is adapted to pass.

It is found in practice that the luminosity of the flame may be further increased by the use of such a plate which serves to conduct the air over its heated surface and thence through the holes therein thus permitting the air thus heated to enter the flame from the inside of its tubular surface to again assist combustion and a further decomposition of the particles of carbon.

The invention further consists in the provision of a. battle plate set upon the first named plate for deliectingthe heated air radially outward as it rises through the holes in the plate causing itI to immediately enter the flame.

rlhe invention further consists in the pri vision of a central. draft hole in the plate which further assists in spreading the flame and intensifying the illuminating effect.

l/Vith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described. and particularly pointed out in the appended claims.

ln the accompanying drawings:

Fig. 6d is a view of the center member of the burner detached with my improvements connected thereto also illustrating the fingers which engage the wick tube for determining the position of the. serrated plate relative to the wick.

Referring to the drawings l0 designates a well-known type of oil burner of the tubular or center draft construction, only such portions being shown as is necessary to illus trate the operation of my present invention. The wick 12 is in a tubular form adapted to be raised and lowered by the usual means (not shown). This wick is mounted in the circular chamber 1l between the walls i3 and lll. The tubular form of flame in this type of lamp is supplied with atmospheric air on its out-side through the multiplicity of openings in the outer wall Y15 and on its inner side by air rising through the center tube 16, and through the perforations 17 in the tubular cap 1S which is removably secured in the center tube ist.

My invention consists primarily in the provision of means for breaking up, dividing or separating the tubular flame as it rises from the wick in order to permit more of the'oxygen of the atmospheric air to mix with the flame to insure a more perfect combustion and produce higher luminosity. To accomplish this in a simple and practical manner, I have provided a. plate 19 which may be constructed of'any suitable material such as nickeled-steel, tungsten or other material'which will not crumble or be consumed by being heated continually or continuously to a very high temperature and around the periphery of this plate or disk, I have formed a multiplicity of tapering or pointed fingers or members 20. Those illustrated in vthe drawing are of a saw tooth shape and are found to produce excellent results in practice, but lingers or projections of any shape and supported in any desired way may be employed to produce a dividing or separating effect upon the flame.

It is found in practice that the best results are obtained by inclining the points of these lingers downward on an angle so that they will stand slightly outward permitting their points or extremities to extend into the flame and divide the same into a multiplicity of streams corresponding in number lto the spaces between the teeth or fingers.

In adapting this plate to the tubular or center draft burner lamp, I have mounted this serrated plate on the upper end of the short perforated tubular cap 18 so that the pointed ends of the fingers or teeth when positioned shall be located a predetermined distance above the wick tube so that it will engage the flame at a substantial distance above its source.

It is found in practice by heating the air prior to entering the fiame, that a more perfect combustion is obtained. To accomplish this, I have provided a series of cone shaped cavities or holes or apertures 21 in the plate 19 whereby the air is permitted after passing over this heated plate to move upward through these apertures or auxiliary air supply and pass into the flame above the point where it has been divided. To better control the flow of this auxiliary air supply, I have provided a` baffle plate 22 which is composed of a ring, see Fig. et, having its center portion 23 removed and a plurality of fingers formed therein, which fingers are passed through corresponding openings 25 in. the serrated plate 19 and clenched, see Figs. 2 and 5, to secure the two plates together. The outer edge portion of this bafile plate is set on an angle and above the opening 2l through the serrated plate, whereby the air rising therethrough 'is deflected outwardly and directed into the dame.

Some different makes of center draft'lamps Y support their tubular cap member in different ways, and in order to insure the proper distance of the flame dividing points, rela tive to the wick tube, I have formed a number of hook shapedmembers 26, see Figs 2 and 6, having outwardly turned ends 27 which'are adapted to engage the upper edge of the inner tube member 14 and so effectually determine the position of the flame affecting portions, relative to the wick tube.

By the application of my simple attach ment to the .lamp of theordinaryY center draft burner a much more perfect combustion is obtained producing a brilliant substantially white flame of` greatly increased illuminating value over that of the flame which has a reddish cast.

When an oil stove having this type of l burner is provided with my attachment, the additional oxygen permitted to mix with the flame greatly increases its number of heat units, thereby rendering such a stove much more efficient as a heater with the given quantity of fuel. Then again owing to the perfect combustion obtained by my improved device the objectionable odor which is caused by unconsumed particles of carbon is entirelyA eliminated.

I have shown and described means for dividing the flame into a multiplicity of streams but any means applied to an oil burner for acting upon the flame to divide or separate the same into a multiplicity of streams will fall within the spirit and scope of my invention. Y V
